Description

Technical Field

[0001] The utility model relates to the field of engineering blasting, in particular to a charging device for water pressure blasting. Background Art

[0002] Hydraulic blasting uses water as the explosive medium, and utilizes the incompressibility of water to the blast stress wave propagating in water, so that the explosive energy is transmitted to the surrounding rock of the blast hole through water with almost no loss, which is very beneficial to rock crushing. At the same time, the "water wedge" effect produced by the expansion of water in the explosive gas is conducive to further crushing of the rock. The presence of water in the blast hole can play a role in atomization and dust reduction, greatly reducing harmful effects such as dust, air shock waves, flying rocks and noise. Therefore, at the operation site, in order to achieve the effect of hydraulic blasting, it is usually carried out by first "injecting water" into the blast hole and then backfilling it with "blast hole mud" to block it.

[0003] However, the rock mass is full of various cracks and fissures, and the rock absorbs water on its own. The injected water will be lost in a short time, thus losing the effect of water pressure. There are already many mechanical equipment at the blasting site and the environment is poor, especially for open air. Some scenes have less water resources. If water pressure blasting is required, additional water must be transferred from other places, and suitable equipment is required for water injection. If plastic bags are used for packaging, rock debris in the blasthole can easily scratch the plastic bags and cause ruptures. Moreover, when plastic bags are used, the explosives will also change position due to shaking in the water, thus affecting the blasting effect. Utility Model Content

[0004] The utility model aims to provide a charging device for water pressure blasting in view of the problems in the prior art that water in the blasthole is easy to lose, the water source is limited and the water injection method is troublesome, the plastic bag packaging is easy to break, and the position of the explosives is difficult to fix.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A charging device for water pressure blasting comprises a tube body and a sealing cover. The tube body is hollow in which explosives can be fixed. One end of the tube body is closed and the sealing cover is arranged at the other end. Liquid is arranged in the tube body.

[0007] The charging device for water pressure blasting arranges explosives in a tube body, and then injects liquid into the tube body to fill the entire interior of the device. The device has a simple structure and is easy to operate. It effectively overcomes the problem that water is easily lost in the traditional method and avoids the problem of being scratched by rock fragments. In addition, for blastholes with broken surrounding rocks, the tube body serves as a support to prevent the hole from collapsing and the inability to load explosives. It can also avoid the situation where the explosives cannot be loaded or cannot be loaded to a predetermined position when water gushes or there is too much water in the blasthole. It has a good heat insulation effect when a high-temperature blasthole environment may be encountered in the use scenario, preventing adverse effects on the explosives arranged in the tube body.

[0008] As a preferred embodiment of the utility model, at least one slide groove is provided on the tube body, and a built-in sliding frame is slidably provided on the slide groove. Since the built-in sliding frame is slidably provided in the tube body, the built-in sliding frame can be slid out of the tube body, and the built-in sliding frame is a semicircular frame, which is convenient for installing explosives, detonators, etc., and is also convenient for adjusting and fixing the position to prevent the explosives from shifting, thereby affecting the blasting effect.

[0009] As a preferred solution of the utility model, the outer contour of the built-in sliding frame is a semicircular body, and the diameter of the built-in sliding frame is adapted to the inner diameter of the tube body. Since the built-in sliding frame is slidably arranged in the tube body, the diameter of the built-in sliding frame should be slightly smaller than the inner diameter of the tube body.

[0010] As a preferred solution of the utility model, the built-in sliding frame is divided into a plurality of installation sections, and the length of the installation section is equivalent to the length of a portion of explosive roll, which makes it possible to well control the position of the explosive arrangement and the spacing between each portion of explosive roll when installing the explosive.

[0011] As a preferred embodiment of the present invention, the explosives are continuously arranged on the installation section, or the explosives are arranged at intervals on the installation section. Since different requirements for blasting effects are required in different scenarios, it is necessary to control the blasting effects by changing the amount and arrangement of the explosives. Therefore, it is necessary that the explosives can be continuously arranged on the installation section, or the explosives can be arranged at intervals on the installation section.

[0012] As a preferred embodiment of the present invention, the volume of the liquid accounts for 40% to 70% of the volume of the tube body. In order to comply with the requirements of the "Explosive Safety Regulations" on the sealing length, the liquid in this device is the sealing mud, so the volume of the liquid is required to meet 40% to 70% of the volume of the tube body.

[0013] As a preferred embodiment of the utility model, an injection port is provided on the sealing cover, and a sealing cap is provided in the injection port. The injection port is provided to facilitate the injection of liquid after the explosive is loaded into the tube body; since the charging device for water pressure blasting may be tilted or inverted during the installation process, in order to prevent liquid leakage, a sealing cap is provided in the injection port to achieve sealing.

[0014] As a preferred embodiment of the utility model, a wire port is provided in the middle of the sealing cover. The wire port is provided because the explosive needs to be detonated using a detonator and a detonator leg wire, or a detonating cord, and the explosive is arranged in the tube body, so the wire port needs to be provided for leading out the detonator leg wire or the detonating cord.

[0015] As a preferred embodiment of the utility model, the explosive is provided with a detonator and a detonator leg wire, one end of the detonator leg wire is connected to the detonator, and the other end of the detonator leg wire extends to the outside of the tube body through a wire opening; or the explosive is provided with a detonating cord, and the detonating cord extends to the outside of the tube body through a wire opening.

[0016] As a preferred solution of the utility model, a water level observation window is provided on the side wall of the tube body, and the observation window is provided for observing whether the liquid meeting the requirements is injected into the tube body.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] The charging device for water pressure blasting arranges explosives in a tube body, and then injects liquid into the tube body to fill the entire interior of the device. The device has a simple structure and is easy to operate. It effectively overcomes the problem that water is easily lost in the traditional method and avoids the problem of being scratched by rock fragments. In addition, for blastholes with broken surrounding rocks, the tube body serves as a support to prevent the hole from collapsing and the inability to load explosives. It can also avoid the situation where the explosives cannot be loaded or cannot be loaded to a predetermined position when water gushes or there is too much water in the blasthole. It has a good heat insulation effect when a high-temperature blasthole environment may be encountered in the use scenario, preventing adverse effects on the explosives arranged in the tube body.
